As the title says, this is a broken mechanic cuz you can go a villager town and put all the villagers into one vehicle of this mod. I am using another mod called "Carry On" so i can carry them until the vehicle and i can stack them in the same vehicle. I want to fix this cuz we are playing on a server and people are starting to abuse of this.

Thanks bro, i really love this mod, one of the bests in my server :)

Stacking entities is a carry on feature, and works on every vehicle. It's not Aircraft related :)

Thank you for your fast answer, keep the good job <3
